The Black Knight is a 1954 British-American Technicolor medieval adventure film directed by Tay Garnett and starring Alan Ladd as the title character and Peter Cushing and Patrick Troughton as two conspirators attempting to overthrow King Arthur.

[4][5] It is the last of Ladd's trilogy with Warwick Films, the others being The Red Beret and Hell Below Zero based on Hammond Innes' book The White South.

The blacksmith and swordsmith John (Alan Ladd) is tutored at the court of King Arthur (Anthony Bushell), but as a commoner he can't hope to win the hand of Lady Linet (Patricia Medina), daughter of the Earl of Yeonil (Harry Andrews).

Sir Palamides tricks the Lady Linet into his castle to try to get her to reveal the Black Knight's identity, but John is informed of this and saves her, still in disguise.

Sir Ontzlake then sends him to King Mark's castle, where a pro-Arthur woodcarver shows him a secret tunnel into the royal chambers.

According to Forbes's memoirs, Alan Ladd's wife and long-time agent, Sue Carol, had script approval and objected to a scene where her husband's character stole a horse.

[12] Donald Sinden, then a contract star for the Rank Organisation at Pinewood Studios, had a permanent dressing room in the same block as Ladd's.

[14] One critic, Jeffrey Richards, thought Ladd badly miscast, "playing the part like a tired American businessman prevailed upon to take the lead in a revival of Merrie England".

By contrast Andrews and Bushell "played their parts for all and more than they were worth, giving every one of the pseudo-archaic line (e.g., 'Away with him, his presence doth offend our sense of honour') the full treatment: resonant Shakespearean delivery and Lyceum flourishes".
